5 CHEMICAL rmn-nx'rmoursnme DEVICE.

To all whom it mag concern.-

Be-it known that I, QLU 'F. AALBUE, a citizen of the United States andresiding at Brooklyn, in the county of Kings and State of 'New- York,have inventedcertain new and useful Improvements in Chemical Fire-Exting'uishing Devices, of which the following. is a specificatiom'suchas will enable those skilled in theart to which it appertains to makeand use the same.

This invention relates to what are known as chemical fire extinguishingdevices or apparatus, and the object-thereof is to provide a device orapparatus of this class inwhich carbonic acid gas under high pressure isused as a chemical element for the purpose specified; a further objectbcing'topr'ovide an improved container for the carbonic acid gas andimproved means for-filling said container with the said gas anddlscharging said gas from the container .and the mingling-thereofwitlrthe other element or elements employed.

The invention is fully disclosed in the 01- lowing specification, ofwhich the accompanying drawi'n forms a part, in which the separate parts0 =my improvement are designated'by suitable reference characters ineach of the views, and in which Figure 1 is a sectional sideview showingthe main part of 1 chemical fire extin ing apparatus made'according tomy invention with the carbonicacid gas container in fulllines;

Suspended from the top 0 i the flange or rim a is 'an openwork strainertube -b .pre'fembly composed of wire mesh 'and provided ish- I rod isSpecification 0,! Letters Patent. Batefited Mar. 27,1917; Applicationfiled April 21', 181 6. sc -an 1a., 2,010. I

.In the bottom of. the plug d is a conical V p as container 0 which ismade' n t'l1e' -for rn c a tube and. com osed of sheet metal capable ofresisting a high degree of. pressure,'and the top of which is-closed'bychamber d in which is placed avertically movable valve e, and thebottom. wall .of

the plug :1 is provided'with radial pins'or similar devices 6 whichproject into the bot:
